Another big name in tech has outperformed estimates this week. Microsoft, Inc. (MSFT) posted fiscal 3rd quarter EPS of 45 cents per share after the market close on Thursday. This beat the Zacks Consensus Estimate of 42 cents per share on revenues that hit $14.5 billion, a new record for the company.

Windows sales were up 28% year over year on strength of its Windows 7 system, which made its debut in October of last year. The company boasts that 10% of PCs worldwide now run Windows 7. These results go along with recent reports by Gartner and IDC, which cited an increase in PC sales for the calendar first quarter 2010.

Microsoft shares had been trading down a bit on the day until an hour or so before the market closed, when they inched up briefly to $31.50. But as we saw with Yahoo! (YHOO) yesterday and Google (GOOG) last week, the company’s earnings beat resulted in a sell-off of shares after the closing bell. Microsoft is still trading in its highest range year-to-date, so perhaps traders had already priced-in the good news. That said, MSFT is down 4% in the after-market.

Recent analyst estimate revisions had been mixed, with a negative near-term bias but a positive longer-term one. Three analysts had lowered 3rd quarter estimates in the past week, but over the past 30 days, 7 analysts had increased their fiscal 2010 estimates (ending June). The current Zacks Consensus Estimate for the fiscal 4th quarter is 45 cents per share, and $2.02 per share for fiscal 2010. Microsoft did not offer guidance.
